Unconventional shale reservoirs in Western Canada, host the majority of Canada's known natural gas resources as well as significant volumes of hydrocarbon liquids. These reservoirs include no to variable, and poorly predictable amounts of hydrogen sulphide and hydrocarbon liquids. In order to predict the distribution, abundance and anticipate production rates of hydrogen sulphide and producible fluids from unconventional reservoirs, a multi-faceted, three year study is proposed that is designed to meet both short and longer term exploration and development needs of industry, environmental management, and resource stewardship. The study will further identify optimum methods for well site and mid-stream treatment of low concentration hydrogen sulphide gas and identify optimum biocides or other treatments to inhibit in situ formation of sour gas. The results of the study will assist the Crown in providing stewardship of the resources and for evaluating and mitigating the environmental impact of sour gas and liquids development. The study will provide factual data to stake holders on risks and hazards. The deliverables of the study will be detailed mapping of produced gases including hydrogen sulphide, and liquids. The predictive maps would be based on fields studies, geochemical modeling and laboratory tests that will include analyses of the selective diffusion, solution, and adsorption of hydrogen sulphide in the presence of other fluids. The data and models will provide both industry and regulators critical information for the design of exploration and development programs including environmental management of hazardous gases.

加拿大西部的非常规的页岩水库拥有加拿大已知的大多数天然气资源以及大量碳氢化合物液体。 这些储层包括可变的含量，硫化氢和碳氢化合物液体的可预测量较差。 为了预测非常规储层的分布，丰度和预期硫化氢和可生产的液体的生产率，提出了一项多方面的三年研究，旨在满足短期和长期探索和长期探索和发展的需求，环境管理和资源管理。 该研究将进一步确定低浓度硫化氢气的孔位点和中途处理的最佳方法，并确定最佳的杀菌剂或其他处理以抑制原位形成酸气。该研究的结果将有助于官方提供资源管理，并评估和减轻酸气和液体开发的环境影响。该研究将为风险和危害的利益持有人提供事实数据。 该研究的可交付成果将详细介绍产生的气体，包括硫化氢和液体。 预测图将基于现场研究，地球化学建模和实验室测试，其中包括在存在其他流体的情况下对硫化氢的选择性扩散，溶液和吸附。数据和模型将为勘探和开发计划的设计提供行业和监管机构的关键信息，包括危险气体的环境管理。
